An authenticated user with workflow edit access could inject arbitrary JavaScript into the Chat Trigger's generated page by setting a malicious webhookId. When a logged-in user visited the chat URL, the injected code executed in the n8n origin with that user's session privileges.
The issue has been fixed in n8n versions 1.123.55, 2.25.7, and 2.26.2. Users should upgrade to one of these versions or later to remediate the vulnerability.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
@n8n/n8n-nodes-langchain.chatTrigger to the NODES_EXCLUDE environment variable.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
